Okay, so, there's this little movie where there are hundreds of people on Earth with supernatural powers. This movie is called Push, where the protagonist possesses telekinetic powers.

It's already been established that humans and dreamkeepers are not aware of each others existence. But, that's the magic of wild, what-if speculation!

What if they WERE aware of each other? If you took Push and combined it with the graphic novel DreamKeepers, you've got yourself a movie where people see their dreamkeepers in the Dreamworld while in their sleep. And, like the Bleeding Effect in Assassin's Creed, they eventually start to gain their dreamkeeper's powers.
